High-Throughput 3-D Digitization of Pinned Insect Collections

LANS Informal Seminar

Abstract: This talk will describe the design and prototyping of hardware and software to address the problem of rapid and reliable 3-D digitization of very large collections of pinned insects. Using the collection at the Field Museum of Natural History as a use case, a pipeline to ingest of the entire collection of 4.5 million specimens in 1-2 years imposes a few-second limit on average processing time per specimen. I will outline the design and implementation of multi-camera systems capable of rapidly capturing light field imagery for 3-D reconstruction of label surfaces and specimen in single snapshots consistent with this time constraint. With imagery captured by using these prototype multi-cameras, I will describe methods under development for 3-D reconstruction of pinned insect specimens and for automatic processing of text on label surfaces. This work was performed as an LDRD project with Mark Hereld (MCS) and summer research interns.
